Solar Telescopes

There are three solar telescopes, two of which are now used for astronomical research, also known as solar towers due to their construction. The 60-foot (18 m) tower telescope was completed in 1908, and the 150-foot (46 m) tower telescope was completed in 1912. The Snow solar telescope, built in 1904 is used for educational demonstrations. The telescopes are used to study helioseismology and other changes in the sun's nature.
